dropDownList using ajax

Question

I used 3 ddl for address purpose using ajax extention (script manager and update panel)
they worked but when user never select any country,state or city and submit then header for each ddl (select country,select city,select state) stored in database.

then You have to validate it before inserting to database. Ex: within insert button click event write below code if(ddlCountry.SelectedIndex==0) { lblmsg.text=select country; return; } if(ddlCity.SelectedIndex==0) { lblmsg.text=select city; return; } if(ddlstate.SelectedIndex==0) { lblmsg.text=select state; return; } after this code insert data to database. you can also use javascript if any problem rply

In page load bind the dropdown by checking postback ex- if (!IsPostBack) { Bind(); //or your dropdown bindcode }
